Sunsteel Strike can bypass Tera Shell
Requested in a comment. Since many questions are popping up, Solgaleo was obtained with save modification and Terapagos was generated using encounter codes. These are both done for testing purposes only.
Done both to contribute to the battle mechanics research effort at Smogon and for my own personal curiosity. These videos are made public since Indigo Disk in case anyone stumbles into them and finds them helpful or informative. All the videos can be found in the playlist below, including ones not visible directly on the channel.
